Making sure I understand, in emocon5's picture the POI for the bottom center image would be at the top of the post? or would it be elsewhere?

No the POI won't be at the top of the post. It would most likely be about 5" low at 100 yards. Did you look at my 2 images? I show why if the post isn't centered your point of impact and point of aim won't match no matter how much you adjust your front sight for elevation. If you adjusted the front sight to bring the POI up you would have to center the front sight post in the center of the rear aperture as shown in emcon's top right image.
